Collecting Coins

题意翻译

Polycarp 有三个姐妹(?),她们分别叫 Alice, Barbara, 和 Cerene。她们都很喜欢收集硬币。现在 Polycarp 结束了他的环球旅行并且带回来了 $n$ 枚硬币。 他对他的姐妹(?)们很好,所以想把他的 $n$ 枚硬币全都分给她们,而且为了公平他希望三姐妹都能拥有一样的硬币。Alice,Babara 和 Cerene 事先各自拥有 $a$,$b$,$c$ 枚硬币。他希望他能够通过分别给 Alice,Babara,Cerene $A$,$B$,$C$ 枚硬币,使得 $A+B+C=n$ 且$a+A=b+B=c+C$。 注: $A,B,C$ 可能会等于 $0$ 。 你的任务是判断Polycarp能否完成他的目标。 每个数据有 $t$ 次询问,你要对每次询问做出`YES` 或`NO`的回答。

题目描述

Polycarp has three sisters: Alice, Barbara, and Cerene. They're collecting coins. Currently, Alice has $ a $ coins, Barbara has $ b $ coins and Cerene has $ c $ coins. Recently Polycarp has returned from the trip around the world and brought $ n $ coins. He wants to distribute all these $ n $ coins between his sisters in such a way that the number of coins Alice has is equal to the number of coins Barbara has and is equal to the number of coins Cerene has. In other words, if Polycarp gives $ A $ coins to Alice, $ B $ coins to Barbara and $ C $ coins to Cerene ( $ A+B+C=n $ ), then $ a + A = b + B = c + C $ . Note that A, B or C (the number of coins Polycarp gives to Alice, Barbara and Cerene correspondingly) can be 0. Your task is to find out if it is possible to distribute all $ n $ coins between sisters in a way described above. You have to answer $ t $ independent test cases.

输入输出格式

输入格式


The first line of the input contains one integer $ t $ ( $ 1 \le t \le 10^4 $ ) — the number of test cases. The next $ t $ lines describe test cases. Each test case is given on a new line and consists of four space-separated integers $ a, b, c $ and $ n $ ( $ 1 \le a, b, c, n \le 10^8 $ ) — the number of coins Alice has, the number of coins Barbara has, the number of coins Cerene has and the number of coins Polycarp has.

输出格式


For each test case, print "YES" if Polycarp can distribute all $ n $ coins between his sisters and "NO" otherwise.
